What are cretin levels?

Cretin levels typically refer to the concentration of creatinine in the blood, which is a waste product generated from muscle metabolism. Elevated creatinine levels can indicate impaired kidney function, as the kidneys are responsible for filtering out this substance from the bloodstream. Measuring creatinine levels is a common diagnostic tool used to assess renal health and overall bodily function. Normal levels usually range from 0.6 to 1.2 mg/dL, but can vary based on factors like age, sex, and muscle mass.
